Method of and apparatus for treating waste gas by irradiation with electron beam

An apparatus for treating waste gas flowing in a waste gas main duct, comprising:

• an electron beam irradiation chamber located exterior to said waste gas main duct for irradiation of any waste gas within said chamber with electron beams from an electron beam accelerator;
• a feeding device having an inlet coupled to an outlet of said main duct and which introduces a part of waste gas to be treated into said electron beam irradiation chamber where said part of said waste gas is irradiated with electron beams thereby to form active species and which feeds the waste gas having said active species formed therein to an inlet of said main duct downstream of said outlet of said main duct;
• a dispersing device disposed in said main duct and coupled to said inlet of said main duct for uniformly dispersing in the main duct downstream of said outlet the waste gas having said active species fed from said feeding device;
• and
• a capturing device for capturing noxious (gas) ingredients in the waste gas within the main duct which have been changed into the form of a mist or dust by the action of said active species.
